Indicates if record multi select is allowed.

<div class="definition">
    Boolean, default = true
</div>

If multi select is allowed, user can select more than one record at a time. This property can be defined
during object creation:

<textarea class="javascript">
let grid = new w2grid({
    name        : 'grid',
    header      : 'Grid Header',
    multiSelect : false,
    columns: [
        { field: 'recid', text: 'ID', size: '50px' },
        { field: 'lname', text: 'Last Name', size: '30%' },
        { field: 'fname', text: 'First Name', size: '30%' },
        { field: 'email', text: 'Email', size: '40%' },
        { field: 'sdate', text: 'Start Date', size: '120px' },
        { field: 'sdate', text: 'End Date', size: '120px' }
    ]
});
</textarea>

Or any time after the grid has been created:

<textarea class="javascript">
grid.multiSelect = true;
</textarea>

You can optionally enable <span class="property">.show.selectColumn</span>. See <a class="argument" href="w2grid.show">w2grid.show</a> for
more information.
